An enormous black hole has been spotted in the sun - but do not fear, it doesn't spell the end of our solar system. Instead the giant dark spot is a gap in the sun's corona - its scorching hot atmosphere. Holes in the sun's atmosphere are a regular feature and Nasa's Solar Dynamics Observatory (SDO) has detected a particularly large one covering the northern hemisphere of our star.

Why are sunspots darker than the rest of the Sun? Sunspots appear dark (in visible light) because they are much cooler than the rest of the surface of the Sun. However, even though they appear dark, they are still very hot. Sunspots have temperatures around 6,300 Fahrenheit (~3,500 Celsius) while the surrounding surface of the sun has a temperature of about 10,000 Fahrenheit (5,500 Celsius). If a sunspot was alone in space, it would glow brightly.
